Abstract (en)
[origin: US5468591A] An ablative recording element comprising a support having thereon, in order, a barrier layer and a colorant layer comprising a colorant dispersed in a polymeric binder, the colorant layer having an infrared-absorbing material associated therewith, and wherein the barrier layer comprises a vinyl polymer having recurring units of the following formula: <IMAGE> wherein R1 and R2 each independently represents a halogen atom; a haloalkyl group with at least one halogen atom in its beta -position of the carbon to which R1 or R2 is attached; a ketal group; an acetal group; a thioketal group; a thioacetal group; a substituted or unsubstituted alkyl group; or a group containing a double or triple bond between any two atoms, one of which is adjacent to the carbon to which R1 or R2 is attached; with the proviso that at least one of R1and R2 represents a group containing a double or triple bond between any two atoms, one of which is adjacent to the carbon to which R1 or R2 is attached; or R1 and R2 may be joined together to form a ring.
